Why does my Echo SRM-225 gas trimmer stall or bog down?

My ECHO SRM-225 starts on cold setting but dies out soon after, sometimes one to three minutes, sometimes just a few seconds. Throttling always makes it bog down and stop. I recently replaced fuel line and filter (Echo 90097 kit) and still, no better. I have been using TRuFuel 50:1 with no problems for months until now. I checked the plug, not dirty at all. I just checked the spark arrestor screen, and it was clean. The one thing I do notice is an accumulation of grease/oil near the exhaust.

elgitano, 4 common things are gas cap venting plugged(loosen cap to see if it runs better). 2nd spark arrester screen plugged, remove and clean the muffler and screen and check exhaust port for carbon accumulation, scrape port clean while holding with port position down or use vacuum so debri will not fall in cylinder when cleaning(carbon debri could harm cylinder walls and rings). 3rd is carburetor out of adjustment,(you may have to adjust the carburetor high or low jet screws) to achieve normal running condition.

4th If none of the above seem to help chances are the diaphragms in carb. need replaced/ rebuild and clean carb. Check the attached links,instruction and guides, Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.

I appreciate the quick reply L Pfaff. I've actually watched all 4 of these videos today, but will review them to see if I may have missed something.

I failed to mention that I had previously pulled the carburetor apart, but it looked quite clean and in order (i did not replace diaphragms though).

Then, I replaced the fuel lines and gas filter, including the primer bulb. I checked the spark arrestor screen (it was clean) though I did not invert to vaccuum out any possible debris. I had also tried to run it with the fuel cap loosened with no luck.

I have one question concerning the high and low jets- honestly, I don't know where they are on this SRM-225.

I will clean/scrape/vaccuum exhaust port and check diaphragms more closely, and if I can find adjustment screws for jets, I will try them as well.

Definitely very helpful and I appreciate the detailed answers, L Pfaff.

I will be back on to let you know how things are progressing and mention the solution.

Carburetors on these things are notoriously finicky. It's unlikely the diaphragm needs to be replaced, but it is likely that one of the tiny little passages is clogged. Use a can of spray carb cleaner to make sure all the passages are clean. Inside the main metal part of the carb you'll see a number of tiny holes on the sides, make sure all of them are unclogged (liquid should come out of them when you spray into a corresponding hole in the carb). I know this sounds a bit vague, but just take the carb completely apart and spray the cleaner into every hole / passage. Sometimes this needs to be repeated several times to get it completely cleaned out. Just because it looks clean, doesn't mean it is. These passages are so incredibly small, it's impossible to tell by looking if they are clean or not. Let me know if this doesn't make sense.

Makes perfect sense. I've done this many times with the mower carb but had never really piddled with gas trimmer engines before. I had a corded trimmer for so long, and this ECHO is a relatively recent addition.

All in all, in my limited garden power tools experience, I like the ECHO trimmer despite the current troubles.

I will definitely do what you have detailed, including the removal and cleaning of the hidden jet.

elgitano, I am happy to here your up and running, I too have picked an idea up from you, a guitar string for using as a probe for ports .010" a good size and cut to what ever length, beats hunting for my welding tip cleaner kit and burning the insulation off twist ties. Have a good day.

Speak out for your right to repair.

New York,

New Yorkers stand up for what they believe in. And we're asking you to
stand up for repair.

This year, New York could be the first state in the nation to pass the Fair Repair Act,
A8192 and
S618.
We have a chance to guarantee our right to repair electronic
equipment—like smartphones, computers, and even farm equipment. We have a
chance to protect local repair jobs—the corner mom-and-pop repair shops that
keep getting squeezed out by manufacturers.

It’s not going to be easy. Manufacturers are standing in the
way. When your stuff breaks, they want to be the only people allowed to fix it.
So far, they’ve managed to stop Fair Repair legislation before your
representatives get a chance to vote on it. We’ve got to be louder than their
lobbyists.

The Fair Repair Act, known as
A8192 and
S618,
requires manufacturers to provide owners
and independent repair businesses with fair access to service information,
security updates, and replacement parts. Tell your state representative to
support S618. Tell them you believe repair should be fair, affordable, and
accessible. Stand up for your right to repair.

Massachusetts,

The people of Massachusetts have always stood up for their
right to repair. In 2012, voters passed a law that ensured
residents' right to repair their car wherever they wanted.
Now, it's time to do the same for electronics and other equipment.

With the Digital Right to Repair Act,
H.143
and S.96,
we have a chance to guarantee our right to repair electronics—like
smartphones, computers, and even farm equipment. The Digital Right to
Repair Act requires manufacturers to provide owners and independent repair
information businesses with fair access to service information, security
updates, and replacement parts.

But we need your help. Big manufacturers don't want this
bill passed. And they're working hard to defeat it.

If you think you have a right to repair your products, find out who
represents you in the Massachusetts legislature. Tell them repair is good
for the environment, good for consumers, and good for business. Tell
them you support the Digital Right to Repair Act, S.96 and H.143.
